Ghost Gunner Tooling
A dull tool may fail to remove an adequate amount of material. The recommended ¼” custom carbide end mill typically shows signs of wear after completing around eight AR lowers, meaning it may be time for a replacement. Always examine tooling for signs of wear prior to running a cutting program. Using an alternative tool will likely result in the cutting tool stalling. In addition, probing errors will occur if the tool is non-conductive.
If you experience offset cuts when using DD lowers, it is possible that there was an error during the probe operation. Finally, an aluminum chip can result in false probe readings. Make sure tooling is clean of any aluminum chips and vacuum any chip from the workpiece prior to probing. Adjust code to correct for offset pocket position only if you consistently see the same offset in several lowers of the same brand.
Proper Installation
Make sure the collet is properly seated into the collet nut. The collet should snap into the collet nut when turned at a 45-degree angle so that the collet and nut do not come apart. Slide the tool into the collet-nut assembly. Thread the tool-collet-nut assembly onto the spindle. Push the tool all the way into the spindle then tighten the collet nut to ensure that the tool does not walk out while milling. The collet should not be able to fall out of the collet nut once snapped together.
Spare Tooling
For best results, use 80% lowers, jigs, end mills, and bits designed to work harmoniously with the Ghost Gunner. Over time tooling and collets can become worn and unserviceable, spare tooling and collets are available on our website.
